We all know what elephant toothpaste is, but what's the best way to make this massive growing foam? Dr. Lithium from NurdRage has answers. He'll show you the best way to reproduce this chemical reaction to get the best foaming action! This is a classic science class demonstrat ...more

If you happened across our radiation survival guide, you'd know that one of the most valuable lines of defense against radioactive particles is potassium iodide. In the United States, west coasters have quickly depleted the supply of potassium iodide tablets, which leaves anyo ...more

Watch this science video tutorial from Nurd Rage on how to make iodine from sulfuric acid and alkali metal iodide. This is the best way to make elemental iodine from sulfuric acid and sodium or potassium iodide. Warning: Reaction must be done outside or in a fumehood due to p ...more

Try out some home brewed chemistry by crafting your own potassium iodide using elemental iodine and potassium hydroxide, or in more scientific terms: 3I2 + 6KOH == 5KI + KIO3 + 3H2O Potassium iodide is used in anti-radiation pills, but please do not attempt to ingest the che ...more

Most of us have conducted an investigatory science project without even knowing it, or at least without knowing that's what it was called. Most science experiments performed, from elementary to high school students and all the way up to professional scientists, are investigato ...more

Want to make boring old colorless water brighten up on command? Well, you can control the color of water with this little magic trick. Actually, it's not really magic, but a classic science experiment known commonly as the iodine clock reaction, which uses the reactions betwee ...more

Try out this science experiment... a classy chemical demonstration. Watch this video tutorial to learn how to make a foamy elephant toothpaste chemical reaction. There's a reason why they call this elephants toothpaste. Hydrogen peroxide is decomposed to form oxygen gas and w ...more

Will the predicted apocalyptic date—December 21st, 2012—really be the end of the world? In this ongoing five-part series, we examine what would happen if zombies, nuclear weapons, cyber wars, earthquakes, or aliens actually destroyed our planet—and how you might survive. End ...more

Chlorine gas is a very useful oxidant, which was first introduced as a toxic weapon by the German Army. Even today, it's still used as a weapon, most recently in the Iraq War by insurgents. But chlorine gas has more useful (and less lethal) applications, and if you want to lea ...more

When I think of nuclear power plants, clean, safe, efficient energy isn't usually the first thing to come to mind. Firstly, I think of Chernobyl, where the world's most devastating nuclear power plant disaster happened in the Ukraine. Deadly explosions released radioactive plu ...more

In the wake of the recent tragedy in Japan, Southern Californians have been hyper alert to any news regarding dangerous levels of nuclear radiation drifting over from Fukushima. At this time, official statements from the California Department of Public Health and the EPA are a ...more

Watch this science video tutorial from Nurd Rage on how to make iodine from an alkali metal iodide, hydrochloric acid (HCI), and hydroxide peroxide (H2O2). Warning: This reaction makes small amounts of chlorine gas and should be performed outside or in a fumehood. This metho ...more

The pumpkin is everyone's favorite cucurbit come Halloween time, and while there are only a few types of Halloween-friendly pumpkins out there, there is definitely no shortage of what you can do with them. You can carve faces into them, perform brain surgery, make them sing, ...more

Discover the power of raspberries! Literally. In this NurdRage science video, learn how some crushed raspberries and some titanium dioxide (TiO2) can create a powered dye-sensitized solar cell. Inside a raspberry is something called anthocyanin, which is a flavonoid pigment. C ...more

Try out this science experiment... watch this video tutorial to learn how to illustrate the scientific concept of conservation of mass. This is purely educational, and not as exciting as some other demonstrations, but this does clearly illustrate the concept of conservation of ...more

But elephants don't need toothpaste, do they? Mr. Kent, a Long Island chemistry teacher, is at it again with his after hours experiments. We like to refer to him as Mr. Wizard 2.0. Elephant's toothpaste is what science geeks call this foamy reaction. Chemically it is the dec ...more

This video shows you an alternative procedure to bismuth subnitrate, using Pepto-Bismol tablets. You'll learn how to test for alkaloids, similar to a toxicology report. Put on your goggles, for this great home science experiment. Ingredients: *1. Transfer two Pepto-Bismol tabl ...more

Although this may not be the most likely disaster you will deal with, it never hurts to be prepared. Knowing what to do and where to go after a nuclear bomb has exploded will give you the best chance of surviving the radiation . Step 1: Get potassium iodide Have potassium io ...more
